EXPERIENCE & QUALIFICATIONS Cips <br />"The design team at AE2S has been great. They are very knowledgeable, <br />good at communicating with staff to determine needs, thorough, and <br />responsive. We are very impressed with AE2S." <br />TOM WESOLOWSKI, PE, City Engineer <br />twesolowski©ci.shoreview.mn.us <br />651-490-4600 <br />Shoreview, Minnesota <br />WATER TREATMENT PLANT DESIGN AND CONSTRUCTION <br />Concerns Lead to New WTP <br />The City of Shoreview provides <br />an average of approximately 3 MGD of <br />potable water to its 26,000 local residents, <br />as well as to customers within the Cities <br />of North Oaks, Arden Hills, and Vadnais <br />Heights. The City experienced significant <br />growth in the 1970s and 1980s, but <br />focus shifted from new development <br />to infill and redevelopment. The City <br />currently operates a water supply system <br />that consisted of six wells, raw water <br />transmission piping, a storage reservoir, <br />chemical feed systems, and a booster <br />pump station (but no treatment/filtration <br />facility). The existing water system had <br />served the City well for decades, but <br />increasing color -related concerns and <br />aging infrastructure spurred the City to <br />enlist AE2S to design and construct a <br />water treatment plant (WTP). <br />Treatment Objectives Drive <br />Technology Selection <br />The treatment objectives established <br />for the new WTP included ammonia <br />removal, iron and manganese removal, <br />hydrogen sulfide removal, radon <br />removal, fluoridation, disinfection and <br />maintaining a protective disinfectant <br />residual in the distribution system, and <br />disinfectant by-product control. Several <br />alternative technologies were evaluated <br />to accomplish these treatment objectives <br />for the proposed water treatment facility. <br />Analysis included a pilot study evaluating <br />greensand filtration and alternative <br />oxidation processes. <br />Solution Meets Treatment Financial <br />Objectives <br />Ultimately, aeration, with gravity <br />filtration, gas chlorine, and traditional <br />backwash reclamation basins were selected <br />as the alternatives that best met the City's <br />needs, both in terms of accomplishing <br />treatment objectives and financial <br />considerations. <br />Final design and bidding were <br />completed in May 2015. The WTP <br />became operational December 2016. <br />—4000 <br />WHY THIS PROJECT? <br />• Integrated with Existing Campus <br />• Iron & Manganese Removal <br />• City's First Water Treatment Plant <br />• Operator Training/Support <br />AE2S CITY OF RAMSEY DESIGN & CONSTRUCTION - MUNICIPAL WATER SUPPLY TREATMENT PROPOSAL 2.4 <br />
